Avoid racing on signal delivery with thread signal blocking in thread
groups.

The method to do this is to eliminate the per-thread sigmask_lock, and
use the per-group (per 'process') siglock for all signal related
activities.  This immensely simplified some of the locking interactions
within signal.c, and enabled the fixing of the above category of signal
delivery races.

This became possible due to the former thread-signal patch, which made
siglock an irq-safe thing.  (it used to be a process-context-only
spinlock.) And this is even a speedup for non-threaded applications:
only one lock is used.

I fixed all places within the kernel except the non-x86 arch sections.
Even for them the transition is very straightforward, in almost every
case the following is sufficient in arch/*/kernel/signal.c:

		:1,$s/->sigmask_lock/->sig->siglock/g

Fix thread-group SIGSTOP handling - the SIGSTOP notification was not
propagated to the parent of the thread group leader.  Now Ctrl-Z-ing of
thread groups works again.

Fix thread group signal sending

This fixes one more race left in the new futex hashing code, which
triggers if a futex waiter gets a signal after it has been woken up but
before it actually wakes up.

This fixes the bug reported by David Mosberger, force_sig_info() dropped
the siginfo structure, which broke things like SIGFPU or alignment-error
exceptions.  This bug was introduced by the threading signal changes.
(The patch also fixes signal declaration whitespaces in sched.h.)

8139too, epic100, fealnx, sundance and via-rhine.

In the process, several of these net drivers gained MII ioctl
locking fixes simply by virtue of being brought in line with
standardized code.

and update all drivers that reference this struct member.

* add boolean 'init_media' arg to mii_check_media
* update all callers (just 8139cp, for now)

* fix eeprom accesses
* fix tx desc overflow
* fix tx timeout bug
* add sis963 support

This URL evaporated long ago, and Alan claims it's not coming back.

Implement a "mapping change" notification for virtual lookup caches, and
make the futex code use that to keep the futex page pinning consistent
across copy-on-write events in the VM space.

the same ignore rules for "tar" as well.

x86-64 has an early console implementation which runs before the normal
console is initialized. To avoid duplicated output it needs to be
disabled when the real console starts. This patch adds an function call
for that to the appropiate part of console_init.

Add the PCI IDs of an AMD 8151 AGP bridge.

Add an AGP driver for the AGP aperture in the northbridge of the AMD Hammer.
The AGP driver works for both 32bit and 64bit kernels.

It also adds some hooks to the AGP driver to allow the x86-64 GART based
IOMMU code to share the aperture with AGP. The hooks are intentionally kept
minimalistic. In addition it needs some Config.in hackery, because AGP cannot
be modular in this case, because the IOMMU needs to control its startup and
it runs early when PCI is initialized.

The original AGP driver was done by Dave Jones, I added the IOMMU support.

Align ELF binary name for x86-64 with ABI.
